T 0 all whom it may concern:

Be it known that SAMUEL P. MURPHY, a citizen of the United States of America, residin at Canastota, in the county of Madison and @tate of New York, has invented new and useful Improvements in Adjustable Bed- Tables, of which the following is a specification.

The purpose of the invention is to provide a table readily adaptable to the head corner post of a bed such as is used in hospitals and the like, the table being capable of swinging movement and being adjustable so that it can be swung toward and away from the patient and have its top adjusted to suit the needs of the patient.

A further purpose of the invention is to provide a device of this character which is simple in construction, durable and effective in operation and inexpensive to manufacture.

Other and further purposes appear in the following description wherein the invention is set forth in detail.

To the exact construction in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claim.

The same numerals of reference designate the same partsthroughout the several figures of the drawing, wherein: V

Figure 1 is a perspective view showing the practical application of the invention.

Fi 2 is aside elevational view thereof.

Fig. 3 is a top plan view, the bed post to which the table is attached being shown in section.

Fig. 4 is a section on the line 44 of Fig. 2.

Fig. 5 is a section on the line 55 of Fig. 3.

As illustrated, the invention is designed for attachment to the corner post 1 of a bedstead partially illustrated in Fig. 1. It comprises a normally stationary arm 2 having at one end a base portion 3 which is formed with a recess semicircular in cross section so that it may embrace the post 1 for half the diameter of the latter where it engages the post. Provided to attach the base portion 3 to the bed post 1 there is a clamping element consisting of the members 4 and 5 each of which is provided with an ear by means of which they are pivotally attached together through the medium of a pin 6. The two members 4 and 5 diametrically opposite the pin 6 are formed with bosses 7 that boss on the section 4 receiving a pin 8 which passes through one end of a hook member 9 and secures it to the boss on the section 4. The bosses 7 on the section 5 is similarly provided with a pin 10, but this pin is designed for detachable engagement with the hook 9 at the end remote from that connected with the pin 8. Obviously, when the hook engages the pin 9, after the two sections have been placed around the bed post 1 and the set screw 11 tightened by setting against the bed post, the clamping member will be firmly secured to the bed post, the arm thereby being rigidly held to the bed post. The clamping member 4 carries the set screw 11 and this set screw passes threadingly through a boss 12 formed on the clamping member and readily through the clamping member 6 for seating against the bed post.

The arm 2 at the end remote from the base 3 is slotted horizontally to provide two spaced ears 13, a second and narrower slot 14 being formed in the arm at the end of the first said slot. Both ears 13 are formed with centrally disposed eyes through which a bolt 15 passes, the latter receiving a wing nut 16 in its threaded end, the wing nut abutting the top face of the ear 13 and the head abutting the face of the lower ear. Positioned between these two arms and in surrounding relation to the bolt there is one end of a swinging or supplemental arm 17. If the wing nut 16 be loose on its bolt this supplemental arm may swing with reference to the arm 2 but if the wing nut be tightened the two ears 13 will be drawn toward each other, the slot 14 permitting such yielding, and a clamping operation will be effected by them upon the end of the arm 17.

The supplemental arm 17 is formed with an upturned end having a clamping element consisting of the members 18 and 19, the latter being formed integral with the arm and the former being pivotally connected with the latter by means of a pin 20 which passes loosely through the ear 21 formed with the clamping member 18 but is fixed in the car 22 formed with the clamping member 19.

The two clamping members at points diametrically opposite the ears 21 and 22 are formed with ears 23, the plane of which is at right angles to the plane of the first said cars, so that a bolt 24 passing through these ears 23 may serve to hold the two clamping members together when its wing nut 25 is tightened. The two clamping members 28 in closed position define a socket in which a knob or ball 26 is received, the latter being centrally disposed and depending from the frame 27 of a circular table having a suitable top 28. When the wing nut is tightened the t TO clamping members efi'eet a gripping operation on the ball 26' so that the table is rigidly held in any position in which it may be caught at the time the wing nut 25 is tightened. Obviously the loosen ng of the wing nut will permit enough slackening of the bolt 24 to permit the table to be shifted angularly in any direction desired.

From the foregoing description and the accompanying drawings, it is believed that a clear enough understanding of the invention is to be had to render further description unnecessary.

The invention having been described, what is claimed as new and useful is:

A device for the purpose indicated comprising a normally stationary arm having a base portion at one end, a clamping element carried by said base portion and consisting of two complemental members one of which is formed integral with the base portion and the other of which is hingedly attached to the first, both members beingformed with bosses opposite the hinge a hook carried by one boss, a pin carried by the other boss and engaged by the hook, a thumb screw threadingly engaged with the hingedly mounted clamping member, and a table carried at the extremity of the arm.

In testimony whereof he afiixes his signature. I

SAMUEL P. MURPHY.
